This SPARQL query aims to retrieve the procurement notice, its publication date, the corresponding lot, and the highest awarded amount along with the currency code for a specific date ("20230905" or 05-09-2023). It does so by specifying a value for the date and then querying the RDF data based on that value. The query returns the information in descending order of the awarded amount, with only the highest value being displayed.
